Title: Zenario CMS 7.0.2d Reflected XSS and Open Redirect Vulnerabilities
Advisory ID: ZSL-2014-5207
Type: Local/Remote
Impact: Cross-Site Scripting, Spoofing
Risk: (3/5)
Release Date: 20.11.2014

Summary

Zenario is a web-based content management system for sites with one or many languages. It is simple to use, and can grow with your requirements.

Description

Input passed via the 'location' GET parameter in 'index.php' script is not properly verified before being used to redirect users. This can be exploited to redirect a user to an arbitrary website e.g. when a user clicks a specially crafted link to the affected script hosted on a trusted domain. Zenario suffers from multiple reflected cross-site scripting vulnerabilities as well. The issues are triggered when input passed via several parameters to 'ajax.php' script is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
